Comment(by godiard):

 I see this again, now with Read activity. The activity icon is no longer
 present in the top frame, then to sugar the activity is no longer running,
 but if you do a "ps" in the terminal, can see the process continues.

 This is a problem to collaboration in the case of Read, because use a port
 to transfer the files, and if another instance is already running, when
 try to open the port get a error and the collaboration is not possible.
 The user don't know what is happening. You can kill the old process from
 terminal, but is not a easy solution.

 I don't know why is happening the error (may be a race condition?) but
 looks like the code can check if self.telepathy_text_chan is None before
 trying to close it.
